SHEET-FILING.

Specification of Letters Patent.

Patented July 9, 190757 Application filed April 24, 1905. Serial No. 257,188.

To allA whom concern:

Be it knownfthat I, TRUMAN 1111.1.,a citizen of the United States `residing at Chicago, in the county of CookandfvStat'e-of Illinois, have invented a certain new and useiful.,-Improvement in Sheet-Filing, (Case 2,) of which'thefollowing'is a full, clear, concise, and exact description,. reference being had to theA accompanying drawings lforming apart o f this specification.

. My invention relates to sheet piling, and its object is to providejections or' improved construction therefor Y which maybe joined together at variousangles and re# 'at one end in a'ball member 2 and at the other end in a socket member 3Qv In Figs. 1, 2 and 3 the ball member is formed by the circular .wings 4 and 5 and the socket member` is formed by thecircular wings 6 and 7 the inner radius of .the-'socket member being practically equal to the-.outer radius of thevball member, and the circular wings may 'be rolled integral with the web portion. The wing 6 preferably extends through an arc of 180 while the wing member 7 practically extends through the arc of 90.l l Thus when .the sections are assembled to form a straight wall, as in Fig. l, the end of the wing 6 will engage one side of theweb of the adjacent member, while when'the sections are disposed at an angle, such as a right angle,-as shown in Fig. 3, the end of the wing '7 will engage the other side of the adjacent web.

, The arcs of these wings, however, may be made of any degree to meet desired conditions. The ends of the circular wings.4 and 5, instead of being separated by the opening 8. may continue to form a complete circle and this ball member may also be entirely solid. The

construction shown, however,`is`the one best adapted for suitable integral nolling'of the section and thej space between the Wings 4 and 5 after assembly of the sections can be lled with filler, such as wood, concrete, or other material usually employed. The'wings 6 and 7 might also be continued to leave an opening between their ends only suiicientto receive the web of the adjacent section, and this opening might be at any part of the socket member, depending upon the angles desired in the wall.

l do not, therefore, wish to be limited. to the-exact construction'shown, but

I claim as new and desire to secure by Letters Patent; 1. in metal sheet piling, the combination of similarl sec`v J tions, each section being rolled integral and comprising-a uniplaner web member, wings extending from one end of the web and .approaching each other to form a ball member, andwings extending from the other 'end of the web and approaching each other to form a socket memben-for receiving the ball member of an adjacent section, whereby the sections are rotatable about each other, the ends of the wings of the socket member being disposed to limit Y the range of rotation of one member about the other `'to 90 degrees. n

2. In metal sheet piling, the combination of similar'secv 65 tions each section being rolled integral and comprising a' u'nplaner web member, wings extending from one end of the web and approaching each other to form a ball member, and wings extending from the other end of the-jweb and approaching each other to form a socket member-for 70 I receiving the ball member of an adjacent section, whereby the sections are rotatable about each other, the end of .one of the wings of the socket member being disposed to "lock adjacent members against further rotation when .said L members reach the same plane, and the end of the other wing of said socket member being,r disposed to limit further rotation of adjacent members with respect to each dther when said members have been brought to right angles- 3. In sheet metal piling, the combination of a plurality of similar sections, each section being rolled integral and comprising a unplaner web portion, a hollow ball member at one end ofthe web portion, and wings extending from the other end of the web portion to form a socket member forreceiving the ball member of :in adjacent section, ad-

jacent members beihginterlocked against further rotation S5 when in the same plane and when at right angles to each other.

4.v In metal sheet piling, the combination of similar scctions, .each` section being formed integral and comprising :L-

web portion, wingsextending from one end of said web portion kto form a ball member, and wings extending from the other end of said web portion to form a socket member for embracing'the ball member of an adjacent section,

said wings and web portion being of the same uniform thickness throughout, the end ofione of the wings of the 9 5 socket member being disposed 'to lock adjacent members against further`rotation when said members are in the same plane and the endot'the other wing of said socket member being disposed to limit further rotation of adjacent members withjrespect to each other when said members have beenbrought to right angles.

In witness whereof, I hereunto subscribe myname-v this 21st day of April A. D., 1905.
